大庆油田萨北北三区东部的分层测压资料应用

Application of the zonal pressure testing data from east part of the north Block 3 in North Saertu, Daqing Oilfield

根据大庆油田萨北北三区东部19口井的分层段压力测试资料,对该区开发效果进行分析评价,结果表明:在非均质多油层分层开采、分层调整的开发模式下,该区目前的层间矛盾、层内矛盾和平面矛盾突出。利用分层压力资料,可以查明不同类型油层的压力水平和分布特点,指导油水井的增产增注措施和其它调整方案的制定,为油田实施挖潜措施和加强套管防护提供科学依据;分层段压力监测技术在老油田高含水开发期的应用具有较为广阔的前景。

The zonal pressure testing data of 19 wells from the east part of the north Block 3 in the north Saertu, Daqing Oilfield, were obtained to evaluate the development efficiency of the block. Under the development mode of separate zone production and adjustment of the heterogeneous multi strata, the block reveals obvious interlayer, inlayer and planar inconsistencies. The zonal pressure data can help to demonstrate the pressure level and distribution of different reservoirs, to efficiently guide well stimulations and other adjustment planning, and to scientifically sustain the implementing of further configuration adjustment and casing protection. The zonal pressure testing technology has a broad application prospect in high water-cut development period of produced oilfields.
